I have not seen a gray catbird in Pittsburgh yet but I know they’re on their way. Next month they’ll arrive from their wintering grounds in the southern U.S., the Caribbean and Central America. How do they get here?
Migratory birds are born with an innate sense of direction and distance to their goal but must learn how to get there on their first trip south. After they’ve made the trip once, they create a mental map and can use the sun, stars, earth’s magnetic field and their sense of smell to return home.
Their sense of smell? Yes! Birds do have a sense of smell and they use it.
